Ultrasound – is it useful when assessing primary open angle glaucoma?

Takeaway

  • Non-invasive A-scan ultrasound effectively measures optic nerve subarachnoid space (ONSAS) changes in patients with primary open-angle glaucoma.

Why this matters

  • Validation of a non-invasive tool to assess ONSAS in primary open-angle glaucoma could make the process of diagnosis less painful.
